Title: Improvements in centrifugal apparatus
IPC: B04B15/02
Filed: 1943-05-10
Abstract: 598,531 . Centrifugal machines. PIAZZA, J. May 10, 1943, No. 7397. [Class 23] A centrifugal apparatus for treating liquids with a gas or vapour, comprises a rotor carrying a number of projecting plates 12, Fig, 1, corrugations or tubes, and a stator carrying similar projecting parts 6, to provide a sinuous passage for liquid supplied through passages in the stator. Steam or other vapour enters at 3 and leaves through a pipe 10. A disc 11 may be hollow or filled with heat-insulating material. Hot or cold fluid circulates through the chambers 8. The Specification refers to fermented must being fed into the casing, the must being centrifuged outwards as a film and treated by the steam entering at 3. The treated must is drawn off through a port 2 which may be V-shaped to prevent escape of steam. The steam becomes charged with alcohol vapour. In a second arrangement, the sinuous passages are formed between corrugations on the rotor and stator. This may be used for scrubbing a gas which enters at 3, by a liquid being centrifuged. In a third arrangement, the sinuous passages are formed by annular tubes secured to the relatively-moving surfaces. Fig. 4 shows a further construction, the rotor having zig-zag plates 15 in between similar stator plates 13. Centrifuged material is collected in a ring 18 and discharged through an outlet 19. Pipes 9 lead a heated, or cooled, liquid into chambers 8. This is discharged through pipes 20 and gases or vapours through a pipe 10. Material to be centrifuged enters through pipes 21. A thermometer 22 is provided.

Title: Improvements in the drying of cement slurry or other quasi-liquid material
IPC: F27B7/20
Filed: 1936-03-12
Abstract: In a method of drying quasi-liquid material such as cement slurry by means of hot gases, the material is caused to travel through two or more successive drying zones, the material in one zone being heated by direct contact with the hot gases and simultaneously heated indirectly by the latent heat resulting from <PICT:0471915/III/1> <PICT:0471915/III/2> <PICT:0471915/III/3> <PICT:0471915/III/4> the condensation of steam which is collected after condensation and discharged separately from the material, this steam being driven off from the material which is located in the second or a subsequent drying zone and which is heated indirectly by the hot gases.  In the construction shown in Fig. 1, slurry is fed on to an endless conveyer 2, which is supported by metal plates 7, 8. Hot gases entering at 5 heat the slurry on the lower run of the conveyer before passing over the slurry on the upper run which is also heated indirectly by steam from the material on the lower run.  The steam is condensed and collected by plates 9 leading to an outlet 10.  A number of conveyers mounted one above another may be used in a similar manner.  In a further construction shown in Figs. 4 and 5, a shell 33 forming the end of a rotary kiln is provided with two internal cylinders 29, 32, Slurry is fed down a shoot 28 into the cylinder 29 and passes eventually by a valve 31 into the annular space between the shell 33 and the cylinder 32. The kiln gases heat the slurry in the annular space indirectly through the cylinder 32, and the resulting steam passes to the outside of the cylinder 29, giving up heat to the material within, which is also heated directly by the kiln gases. The condenser water flows to an outlet 36.  The slurry around the cylinder 32 passes to the kiln proper by way of compartments 39 with closures comprising cam-actuated flaps 40.  In a further construction shown in Fig. 6, the kiln 42 is separate from two concentric cylinders 44, 46.  The slurry is fed to the inner cylinder by a shoot 43 and passes into the outer cylinder from which it is discharged to the kiln.  Steam from the heated slurry in the cylinder 46 passes through openings 47 in a shell 45 surrounding the cylinder 44. The material in the cylinder 44 is heated indirectly by the steam and directly by the kiln gases.  The condensed water is discharged through openings controlled by valves 50.  In a modification the zones in which the slurry is heated may be put under different pressures.
